Alan Pryce-Jones of The New York Times wrote of the novel: "John Fowles is a very brave man. He has written a novel which depends for its effect on total acceptance by the reader. There is no room in it for the least hesitation, the smallest false note, for not only is it written in the first person singular, but its protagonist is a very special case indeed. Mr. Fowles's main skill is in his use of language. There is not a false note in his delineation of Fred."[14] Hayden Carruth of the Press & Sun-Bulletin praised the novel as "brisk" and "professional," adding that Fowles "knows how to evoke the oblique horror of innocence as well as the direct horror of knowledge."[2]
In 2014, Mary Andrews of The Guardian wrote that "Fowles invites us to defy his main character's excuses and read between the lines, and the facts paint a more chilling picture. Fred doesn't accidentally abduct Miranda, there's a sense that he's been leading up to this event his whole life," and deemed Frederick Clegg "one of literature's most evil characters."[15]
